Materialize the complete effective vLLM package before GPU work: exact-commit tracked files, every non-bytecode ignored runtime file, and stable-copied direct symlink target bytes. Freeze it read-only, launch with Python safe-path and a private PYTHONPATH, disable plugins, reject inherited VLLM overrides, and rehash before and after each model.

The portable runtime identity is the sorted logical package paths plus sizes and content hashes, not editable-install metadata or absolute target locations. The complete package digest must travel in generation backend provenance alongside the native-only digest. Complete private vLLM snapshots make B200 generation provenance portable A real CPU-only materialization covered 3,236 files and 553,835,742 bytes: 2,251 tracked files, 985 runtime-untracked files, 13 native extensions, and 2 direct symlinks materialized as regular files. Strict audit validation and actual vLLM package import from the private snapshot passed, and teardown left no snapshot files. How can a B200 generation collector use ignored precompiled vLLM payloads and external native symlinks without leaving mutable runtime dependencies? lab For editable or precompiled ML runtimes, snapshot the entire effective package rather than only Git files or shared objects; reject inherited behavior controls, prove actual import origin, content-bind both package and native subsets, and retain a strict sanitized audit with the result.
